TYPE-WRITING MACHINE.

Application filed Jul 2, 1914. Serial at. 848,618.

To all whom it may concern:

Be it known that we, MARSHALL SAR- GENT and Anvil) E. KARLBERG,citizens'o United States, and residents of Indianap- -olis, in thecounty of Marion and State of Indiana. have invented certain newand'useful Improvements in Type-\Vriting Madeclare the following to be afull, clear, and exact description of-the invention, such as will enableothers skilled in the art to'which it appertains to make and use thesame.

' This invention relates to improvements in typew-ri t'ing machines andmore particu-' larlyfto the universal bar or frame construction and itsrelation to the mechanism with which it co6perat'es,-one object of theinvention. being to reduce the length, force and pounding efiect of thestroke of the key actuated means which control the operation of-s aiduniversal bar or frame. I

A further object is to provide a universal bar or frame structure whichshall-be operated by the key leversin proximity to the fulcrums of thelatter and to so mount an engaging or'abutment pad that it may bereadily adjusted or renewed.

With these and other objects in view, the invention consists in ofconstruction and combinations of parts as hereinafter set certain novelfeatures forth and pointed out in theclaims. v

In the accompanying drawings, Figure l is a sectional view, partlyinelevation, showing a stenographic typewriting machine em-t bodying ourimprovements. Fig. 2 is a parwith the universal shown in front ele- 4are detail views.

frame, suitableguiding devices 'being also provided for directing themovements of the paper and inking ribbon between the type and theplaten. 1

Av universal frame 11 is mounted on the rod or shaft 7, and comprisesuprights l2- 13 connected at their lower ends by a crossbar 14; (whichmay beltermed the universal barpw- 8e) and; connected at theirnpperportions by a crossbar-'15, which latter may consist of two horizontalarms projecting toward each otherand provided with ears 16 through whicha, bolt 17 passes. The ears 16' are spaced apart to accommodate a pawl18 which is-loosely mounted on the bolt 17 and serves to actuate'theink-ribbon mecha-" nism when the universal frame is rocked .by theactuation of a key-lever.

'lhelower ends of'the uprights 12- 13 are bent forwardly and extendbelow the plane of the rod or shaft 7, so, that the universal cross-bar14 shallbe disposed horizontally unde'uthe key-levers slightly inadvance of the pivotal mountings of said key-levers.

A platelt) islocated over the cross-bar 14 and constitutes a holder fora pad 20 to'be engaged by the ground lower faces oredges of thekey-levers. The plate l9.is support ed over. the cross-bar 1-'l by meansof a plurality of screws 21 which pass -u pwardly through the cross-ban.By means of these screws, the pad may be readily adjusted with-relationto the key-levers, and said pad and its holder may be preventedfromjlat-. 22-

eral -displacen ient by means of screws passing through the uprights ofthe universal frame and engaging the ends of the" plate or pad holder.Thevarious screws 21- 2; are provided with lock-nuts 23 to insuretheretention of the pad and its holder in the positions to which they maybe adjusted.

An arm 2e having a is secured to the lugs 16 of bar of the universalframe,

bifurcated lower end the upper "crossand through'the upper-portion ofthis arm, a screw 25 passes the head of said screw consti-.
